agra 66bdc70bf1 test: group examples into per-category folders
Move examples/*.sx and their expected/ snapshots into per-category
subfolders (examples/<category>/...). Folder = leading filename token,
with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus
runner and LSP sweep now discover each category's expected/ dir, while
issues/ stays flat. Example 1058's repo-root-relative companion import
is made file-relative. Path strings embedded in 164 snapshots were
regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// String / byte-pointer FFI baselines. Covers the three shapes
// callers actually use at the sx ↔ C boundary:
// - null-terminated `[:0]u8` (C-style string)
// - raw byte pointer `[*]u8` + length (slice-style)
// - sx `string` decayed to `ptr` (the slice-decay branch
// in coerceArg pulls .ptr)
